史上最難的 SAT 數學題

Hello, I am Ms Alla, a veteran teacher from Maryland who offers a math SAT prep class.
Want to test yourself against the most difficult SAT math questions? Want to know what makes these questions so difficult and how best to solve them? If you're ready to really sink your teeth into the SAT math section and have your sights set on that perfect score, then this is the guide for you.
I put together what I believe to be the  most difficult questions for the current SAT, with strategies and answer explanations for each. These are all hard SAT Math questions from College Board SAT practice tests, which means understanding them is one of the best ways to study for those of you aiming for perfection. 

 I will fully support and lead your learner through test preparation. If I find any gaps, I provide a mini lesson. If you are looking for the highest quality preparation for the SAT,  my sessions  are the way to go.  I have been teaching classes for the SAT since 2003.  I have a  record of helping students make significant improvements in their scores, which has resulted in the opportunity to attend highly selective colleges.   My background includes masters's degrees in engineering, master's degrees in math and education, and teaching certificates in math (high/middle) and Sp Ed.
Topics include:
Weekly rotation of different concepts your student needs to know for the math segment of the SAT.  I target the instruction beginning at the most basic level for each concept, assuming the learners are above average skill level. The class is mostly beneficial for learners who completed Algebra 2 class in school.
Areas:
Word Problems
Linear, Quadratic and Exponential Functions
Operations with Rational Functions
Irrational Numbers
Probability and Statistics 
Operations with Exponents and Polynomials
Geometry problems: Right triangles, Circles, Parallelograms, etc
